Any ideas on what could be the issue ? 

  @Wayne-TP thanks Wayne. I have checked all and still having the same issue. Channel is 1, signal strength on all is -32 to - 50 (RSSI) and the channel width as 20MHz.

At a loss as to what else it could be ?

Having a read through the forum and the above seems to have had the same issue and it was resolved by the team. Is this possible to look at ?

  @Wayne-TP Thanks Wayne. Its looks like the exact same issue. Here is some screenshots. they are local smart actions set in the app. None of them are showing the blue icon that has never appeared for me. Thanks in advance

Hi Wayne Yes this is just one setup. Its random. could be anything from 10 seconds to a minute after the trigger. also seems to be worse after the bulbs have been off for a period of an hour or so. same with the rest of the bulbs. for example i have 5 L630 bulbs that when triggered all come on at different stages during the first minute despite all having the same automation setup

  @Wayne-TP I can send a video if that helps ?
